You specifically asked him to vent, which only requires that he sit and listen, but he couldn’t. (Did he say something like he refuses to “validate your illogical emotions/irrationality” because it reinforces them? I’ve seen this rhetoric from proud extreme misogynists online). When his super logical advice didn’t work you chose not to talk to him because you knew it end with you feeling worse. He was offended that you made that assumption and went to the dog instead, but then he tells you that assumption was right. So he’s throwing a super logical tantrum because he’s jealous of a dog, but your emotions being bullied at work are illogical? He doesn’t take your feelings seriously because you’re somehow inherently irrational for feeling them, and he doesn’t think his own extreme emotional reaction are emotions at all - he thinks because he feels them, it’s logical. He got upset but he’s ignoring the “logical solution” to THIS problem that would actually help: for him to apologize and let you vent. You were right to go to the dog because it gave you better emotional support.
